Reference numeral 45 denotes a stirring motor, and two stirring motors 45 are provided below the lower clamp arm 37. The rotating shaft 47 of each stirring motor 45 passes through the holding plates 39, 39 of the lower clamp arm 37 and the holding plates 39, 39 of the upper clamp arm 37 so as to freely rotate in the vertical direction. The upper end side exceeds the upper holding plate 39 of the upper clamp arm 37.
The drive roller 41 described above is connected to the rotating shaft 47 of the stirring motor 45. The drive roller 41 of the lower clamp arm 37 and the drive roller 41 of the upper clamp arm 37 that are aligned in the vertical direction are connected to one rotating shaft 47, and the lower drive roller 41 and the upper drive are connected. The roller 41 rotates in synchronization.

  An attachment portion of a shaft 35 is inserted and fixedly coupled between two holding plates 39, 39 on one end side of each of the upper and lower clamp arms 37, 37, and two on the other end side. A mounting portion of the shaft 49 is also inserted between the holding plates 39 and 39 and fixedly coupled. Thereby, the upper stage side and lower stage side clamp arms 37, 37 are held in a parallel posture.

  With the above-described configuration, the clamp mechanism 23 is configured to be clamped and released by the integral rotation of the upper and lower clamp arms 25, 25 on the front side. A clamp space 50 having a circular cross section is created inside 25 and 37.

In FIG. 5, the code | symbol 51 shows a container and the container main body 53 of this container 51 has comprised the bottomed cylindrical shape. An annular convex portion 55 having a mountain-shaped cross section is formed on the outer peripheral surface of the container body 53. The annular convex portion 55 is arranged in two lines up and down. A lid 57 is fitted to the upper end portion of the container body 53 and is fastened and fixed by a lock ring 59 to seal the inside.
As shown in FIG. 6, the container 51 is sized to fit in the clamp space 50. As shown in FIG. 3, the container 51 is placed in the clamp space 50 created inside the clamp arms 25 and 37 during clamping. The container 51 is accommodated.
The container 51 having the above-described configuration is adapted to the stirring device 1.

Two guide rollers 29, 29 and two drive rollers 41, 41 are supported by the annular convex portion 55 of the container body 53 of the container 51.
As shown in FIG. 7 (1), on the guide roller 29 side, the annular convex portion 55 hits the pair of sliding slope portions 31, 31 and is slidably supported.
Further, as shown in FIG. 7B, on the drive roller 41 side, the rubber ring 43 hits the rubber ring 43 and is frictionally supported.

Next, the attitude | position of the stirring apparatus 1 at the time of stirring work is demonstrated.
As shown in FIG. 8, after the container 51 is clamped in an upright position, the container 51 is raised to a predetermined height, and the container 51 is tilted by using a rotation mechanism as shown in FIG.
During the stirring operation, the drive rollers 41 and 41 shown in FIG. 7B rotate, and the rotational force is transmitted to the container main body 53 via the rubber ring 43 to rotate the container main body 53. As shown in FIG. 7 (1), the container main body 53 is guided by guide rollers 29, 29 and normally rotates while maintaining a rotation trajectory perpendicular to the axial direction of the container 51.

Since the container 51 is inclined, when the container 51 is rotated, the annular protrusion 55 of the container body 53 tends to be inclined with respect to the drive roller 41 as shown by the phantom line in FIG. Then, the annular convex portion 55 on the side that has been in contact with the guide roller 29 is displaced and becomes unstable as shown by the phantom line in FIG. Since centrifugal force is applied to the guide roller 29, the guide roller 29 cannot maintain its unstable state and slides on the sliding slope 31 to return to the state indicated by the original solid line. Return to the state indicated by the solid line. Since both sides of the rubber ring 43 are also the sliding slope portions 31 in the driving roller 41, the sliding immediately follows the sliding on the guide roller 29 side.
As described above, since the posture maintaining mechanism works, even if the rotating mechanism and the container 51 are separated, the stirring operation proceeds smoothly.

  The embodiment of the present invention has been described in detail above. However, the specific configuration is not limited to this embodiment, and the present invention can be changed even if there is a design change without departing from the gist of the present invention. included.

  The present invention can also be used for stirring and mixing a mixture in the industrial field such as food, chemicals, plastics, and industrial waste while heating.
